Abstract : Arid and semiarid landscapes in regions with seasonal precipitation experience dramatic changes that alter land surface conditions, including soil moisture states, ecosystem productivity and river flooding. These variations in terrestrial properties have implications for vehicle mobility, airborne surveillance, target acquisition and aircraft operations and for battlefield environmental predictions supporting these operations. In this research, we developed and demonstrated novel approaches for terrestrial science studies by integrating the deployment of environmental sensor networks, unmanned aerial vehicle data acquisition and high performance computing-based hydrologic modeling designed to capture, account for and predict seasonal variations in land surface conditions. Our tests are focused in a range of arid and semiarid sites in southwestern North America that are representative of operational environments undergoing strong seasonality.
